The rounded-square / wayfarer design and neutral matte brown finish are classic and suit both men and women across most face shapes. Fit & Size: They are standard adult medium-size frames. They will fit teenagers and adults comfortably, but will likely be too loose for young children or very narrow faces. Current Lenses (Clear Demo Lenses): Right now, the frame only has plain plastic demo lenses fitted. Anyone can wear them immediately as a simple fashion accessory or for light dust/wind protection. Prescription / Power Use: If someone needs vision correction, any local optical shop can remove these demo lenses and fit prescription lenses (single vision, bifocals, reading, or computer blue-cut lenses) into this frame.
